7 Claims.

This invention pertains to an identification ticket, and moreparticularly to the paper stock therefor, including the method ofproducing the same. Such tickets are commonly used for admissions,receipts and as legalized mutual race betting tickets.

The object of the invention is to produce a ticket or paper stocktherefor of a character which may be readily identified for the purposeof detecting counterfeits and preventing erasures and the changing ofvalues or identifying marks printed thereon.

Another feature of the invention is to produce a paper stock from whichthe ticket is out which may be printed in an automatic machine as it isdelivered oped from the interior of the paper stock as distinguishedfrom surface printing by ink.

The use of a coloring dye in the production of paper having reactivewell known in the art and has been applied to so-called safety paper, asoutlined in an article appearing on page 61 of the September 6, 1928,issue of the Paper Trade Journal, a publication of New York, New York.

It is the purpose of this invention to utilize such coloring dye in amanner'to provide a paper stock from which such tickets may be producedto largely overcome, or greatly minimize, the problem of identificationand alteration.

In the use of identification tickets, particularly mutual tickets atrace tracks, substantial losses are encountered through counterfeitingof pay tickets or the alteration of non-pay tickets to pay tickets byapplication of eradicating fluids, scratching and the like. Manyattempts have been made to produce a paper stock to avoid or changingidentification marks such as will indicate to the pay teller that aticket presented is counterfeit or has been altered.

The invention herein set forth not only provides a ready means ofidentifying the paper stock to distinguish the ticket from those of c0unterfeit stock but, so far as is known, eliminates any possibility ofaltering the printed matter. This is in a dye, either neutral or of anycolor, will chemically react through a surface coloring upon theapplication of a suitable agent, and wherein the surface coloring isapplied thereover in such manner as not to resist erasures.

chemical characteristics is The full nature of the invention will beunderstood from the accompanying drawing, the following description andclaims:

Fig. l is a perspective View of a section of stock in the form of astrip greatly exaggerated as to thickness and with successive layerspeeled oil to same ticket after having been identified and accepted forredemption through application of a stamp. Fig. 6 is a modified form ofFig. 5 showing another method of identification for acceptance andredemption through a fingermark.

The paper stock as illustrated in Fig. 1 is developed in the usualmanner on a paper making machine, preferably of three layers of two ormore colors. As illustrated herein, and for example, the outer layersare colored yellow and the inner layer is colored red. Obviously othercolors may be employed. Thus, as in the usual practice in producingticket stock, a red coloring dye may-be applied to the stock carriedover the carried over the rolls on In this instance, the yellow dye, orany other desirable color, is of a character which is reactive to analkaline solution to change its color, the paper fibres of the outerlayer being impregnated therewith. A satisfactory dye for this puras No.364 and the form in which this is marketed is believed to be thedisodium salt as follows:

S OsNa Upon treatment with to red is believed to example, will probablygens with sodium.

This dye is reactive to an alkaline solution of printing type. Suchcolor of the reactive dye such through the surface deemed a stamp 'mayserve three functions.

a pH greater than 16, in that upon such solution being applied, thecolor of the dye will be changed thereby. For example, the abovedescribed dye will so react as to become a reddish pink color;

After the stock is thus developed and built up with the impregnateddyes, it is sized and passed through coloring rolls for applying adifierent surface coloring to the dye impregnated outer layers. Suchsurface coloring may be green, blue, or any other suitable color asshown in Fig. 2. Before applying portant that the stock be sufficientlysized to prevent any material penetration thereof. This results in thesurface coloring being destroyed upon the lightest application oferasure or scratching. Such surface coloring is preferably selected soas to react by a change in color upon application of any of the knownink eradicating solutions.

The stock when thus prepared is ready for trimming, printing and rollinginto suitable rolls for use in ticket vending or totalizing machines, orcutting to ticket size, printing and vending in the usual manner.

Fig. 3 shows a section of a strip of stock wound in a roll after beingpartially printed for use in an automatic ticket printing and vendingmachine.

Fig. illustrates the final printed and cut ticket with the identifyingindicia thereon. This indicia, as shown in Fig. 4, may be applied by theapplication of surface ink in the usual manner of printing. But,preferably, and to prevent erasures, and alterations of the identifyingindicia the printing may be effected by the mere application of analkaline solution upon the type application of the aleffect of changingthe that it will show coloring and in this case develop a printedidentifying indicia comprising the discolored and impregnated dye, asdistinguished from mere surface printing. The result is that suchidentifying indicia cannot'be removed by erasure from the surface of theticket for alteration thereof as is the case with surface applied ink.

A ticket of this character further has the major'advantage of convenientidentification for ackaline solution has the ceptance and redemption.

' As shown in Fig. 5, upon the ticket being reillustrated therein asembodying the word Paid may be applied with the alkaline solutionthereon obtained from first applying the stamp to the usual so-calledink pad which is impregnated with the solution instead of ink. Upon thusapplying the stamp the change in color through the chemical reaction ofthe dye as above referred to will promptly appear. This will be evidencethat the ticket to be redeemed is not a counterfeit.

As suggested in Fig. 6, the redeemer of the ticket need not use a stampbut may moisten his fingers with the alkaline solution convenientlyarranged in a sponge so that when he grasps the corner of the ticket forredemption, the ticket will change color and show his fingerprint. Thisis illustrated in the lower left-hand corner of the ticket illustratedin Fig. 6.

Summarizing the advantages and uses of identification tickets and paperstock therefor made in accordance with this method, the chemicalreacting dye with which the outer layers of the stock are impregnated,and the surface coloring The ticket may be the surface coloring, it isim-' readily identified from a counterfeit ticket by the application ofthe alkaline solution in any convenient manner (Figs. 5 and 6) to effecta chemical change in color. Secondly, the surface coloring will beremoved by mechanical erasure, and will chemically react to the knownink eradicator solutions to the end that any attempt to alter theindicia by mechanical erasure or the use of a solution for eradicatingthe identifying indicia to permit alteration thereof, will immediatelyshow up through non-removable discoloration. Thirdly, it enables the useof a printing liquid containing an alkaline solution, as distinguishedfrom the conventional oil base inks,

for use in automatic ticket printing and vending machines. Such alkalineink, in effect develops its coloring from the die impregnated stock,forestalling any attempt at surface erasure.

Said advantages mentioned will make it difficult, if not impossible, toeither substitute a counterfeit ticket or effect alterations in thelegitimate ticket.

The invent-ion claimed is 1. An identifying ticket including paper stockimpregnated with a coloring dye chemically reactive to a color changingagent and a superficial surface coloring applied over the exposedsurface of the dye impregnated stock without penetration, saidsuperficial surface coloring being of a different color than theimpregnated coloring dye and through which a color changing effect mayappear upon application thereto of a color changing agent through themedium of its reaction to said impregnated coloring dye.
